IMPROVEMENT IN HlLLSlDE-PLOWS.`

Specification forming part of Letters Patent No. 32,587, dated une 18, 1861.

.To @EZ whom it may concern:

Be it known that I, AUGUSTUS SANBORN, o Glover, in the county oi' Orleans and State oi' Vermont, have invented a new and useful Improvement in the Hillside-Plow; and I do hereby deel-are the same to be fully described in the following specification and represented in the aeccompanying drawings, of which- Figure lis a top view7 Fig. 2 a side elevation, and Fig. 3 a rear elevation, of a hillside-plow provided with my invention. Fig. 4 is a longitudinal section of the reversible mold-board and its adjustable wing, the combination and arrangement of which constitute the principal part of my said invention.

The mold-board of the common hillsideplow, owing to the form necessarily required to be given to it, is apt, while the plow is in use, to cause more or less of the earth to rrise over the same and fall between it and the plowbeam. To avoid this difficulty, and to enable the plowto be employed to advantage on level land as well ason a slope, I have combined with the reversible mold-board A an adjustable wing or auxiliary mold-board, B, which is arranged along the middle or course-of the outer surface of the reversible mold-board, and formed as shown in the drawings. This wing B should be hinged to the reversible mold-board; or, as shown in the drawings, it should project from a shaft, a, arranged within a recess or slot, b, made in the mold-board A,the shaft being supported in bearings c c, and being provided at its rear end with an arm, d, arranged at an obtuse angle to the shaxt. The shaft also is provided with a friction spring, g, which projects from it and bears against the rear surface and ree-entering angle of the mold-board. The said wing B may be turned so as to have its front end or part, h, bear against either of the posts or ears i i of the furrow-opener C of the plow, and when turned upward the wing, While the plow may be in use, serves to detieet the earth that may be thrown up by the furrow-opener; or, in other words, to prevent such earth, or any part of it, from passing over the top part of the main mold-board.

The arm d serves to enable a person to move the wing B by means of his foot, while his hands may have hold ofthe handles k 7c or the plow, the spring g operating to maintain the wing in its position while raised upward.

I claim- 1. The' combination and arrangement of the I auxiliary mold-board or wing B with the hillside-plow, or its reversible mold-board A, and to operate therewith substantially as specied. 2. .The combination and arrangement ofthe bent arm d with the wing B and the reversible moldboard, the said arm being to enable a person to move the Wing under circumstances and by means as described.

AUGUSTUS SANBORN.
